Panduit FZ2ELLNLNSNM004 Opti-Core OM4 Duplex LC Fiber Patch Cord
The Panduit FZ2ELLNLNSNM004 is a 4-meter OM4 multimode duplex fiber optic patch cord engineered for 40GBASE-SR4 and 100GBASE-SR10 Ethernet deployments in data centers and high-density structured cabling environments. Built on laser-optimized 50-micron multimode fiber with aqua LSZH jacketing, this LC-to-LC jumper delivers the low insertion loss and modal bandwidth required for 100-meter 100 Gb/s transmission while meeting strict European flame and smoke regulations for enclosed telecommunications spaces.
Key Features
- OM4 Laser-Optimized Fiber: 50-micron multimode core supports 100 Gb/s Ethernet to 100 m and 40 Gb/s to 150 m, backward-compatible with OM3/OM2 legacy infrastructure
- LSZH Jacket Construction: Low Smoke Zero Halogen rating meets IEC 60332-1 and 60754 for installations in poorly ventilated spaces, risers, and European building codes
- Duplex LC Connectors: Industry-standard LC duplex interface provides high port density in SFP+/QSFP+ transceiver modules and fiber patch panels
- 1.6 mm Cable Diameter: Slim profile supports dense cable management in vertical managers, horizontal trays, and rear-of-rack pathways
- Opti-Core Quality Standard: Factory-terminated and tested to meet ISO/IEC 11801 Ed. 2.2 and TIA-568-C.3 insertion loss limits
This patch cord uses laser-optimized 50/125-micron OM4 fiber with a minimum 4700 MHz·km effective modal bandwidth at 850 nm, the wavelength used by multimode SFP+ and QSFP+ transceivers in 10/40/100 Gigabit Ethernet applications. That bandwidth ceiling translates to 100-meter maximum channel length at 100 Gb/s (100GBASE-SR10) and 150-meter reach at 40 Gb/s (40GBASE-SR4), making OM4 the minimum fiber grade for current-generation spine-leaf data center fabrics. The aqua jacket color follows TIA-598-D color coding for instant visual identification during moves, adds, and changes — critical when troubleshooting crowded patch fields where OM3 (aqua) and OM5 (lime green) cables coexist. The LSZH jacket compound produces less than 0.5% hydrogen chloride gas and optical smoke density under 0.5 when burned, a requirement in European Union installations per CPR (Construction Products Regulation) Class B2ca and in any U.S. facility where fiber runs through return-air plenums or vertically between floors without conduit. Standard PVC-jacketed patch cords release corrosive hydrochloric acid and dense black smoke during combustion — acceptable in open office areas but prohibited in telecom rooms, data halls, and transportation tunnels across much of Europe and Asia.
Deploy this cord for equipment-to-panel interconnects in telecommunications rooms, cross-connects between pre-terminated MTP/MPO cassettes in main distribution areas, or direct server-to-switch links in top-of-rack configurations. The 4-meter length suits typical rack-to-adjacent-rack spans in hot-aisle/cold-aisle layouts or switch-to-patch-panel connections when the panel mounts in the same relay rack as the active equipment. LC duplex connectors align with the SFP+/SFP28/QSFP+/QSFP28 transceiver form factors found in Cisco Nexus, Arista DCS, Juniper QFX, and Dell PowerEdge switch platforms — one duplex LC cord provides the Tx/Rx pair for a single 10G or 25G lane, while four cords (eight fibers total via breakout) support a 40G QSFP+ link in parallel optics mode. The 1.6 mm overall cable diameter allows 50+ cords to route through a single 1U horizontal cable manager without exceeding the bend-radius limit (10× cable diameter = 16 mm minimum bend radius), preserving signal integrity and preventing kinking that would elevate insertion loss beyond the 0.35 dB duplex budget at 850 nm. Panduit factory-terminates each connector with epoxy-polish or mechanical splice methods and tests insertion loss on calibrated reference-grade test equipment before shipping — you're not field-polishing connectors or hoping for sub-0.5 dB performance from adhesive-free quick-connect solutions.
Compliant with ISO/IEC 11801 Edition 2.2, TIA-568-C.3, TIA-604-3 (FOCIS-3 SC), and TIA-604-10 (FOCIS-10 LC) physical-layer standards. The Opti-Core line delivers insertion loss within ANSI/TIA Grade-B limits (0.35 dB max per mated connector pair) and return loss better than 20 dB, the performance floor required for error-free 25 Gb/s NRZ signaling per IEEE 802.3by. Use this patch cord when your installation spec calls out LSZH compliance, when local building codes prohibit PVC in vertical or horizontal pathways, or when you need guaranteed OM4 modal bandwidth for 40G/100G Ethernet links in Tier III/IV data center environments where every 0.1 dB of excess loss forces a costly transceiver upgrade or fiber replacement.
